In DeployHQ, you can upload your own custom keypair to one or more projects. This might be useful if you have a number of different projects all deploying to the same servers.
To upload a new key pair, head to the configuration page for one of your SSH servers in any project, then below the current public key you'll find a link to upload a private key. Click this link, then upload your the private key by pasting it in the dialog, then clicking Upload Private Key;
Please note that any previously connected services, in particular your repository will require updating if you upload a custom key, as the same SSH key pair is used to connect to both your repository, and any configured servers in your project.
If you are generating an SSH key locally, you will need to run the following command:
$ ssh-keygen -m PEM
And ensure you skip the option to add a passphrase by hitting enter twice on your keyboard. You can then copy the private key into DeployHQ once it has been generated.
